rear brakes

[packie]

back brake all ready for new bits on monday, the only thing is i cant undo the disc bolts any one know what
size the hex key is ( allan key ) ? or how to undo them easy ?

The previous owner (or factory) could have used thread glue so be careful. The best way forward is make sure you have a good hex bit (I think its a 6mm) from a socket set, but mount it on an impact screwdriver to shock them open. Maybe ever a socket wrench might be good enough. You will certainly have more leverage over a hex key. As mentioned, be careful not to round the screw or you'll be in deeper sh*t. If it's not coming, dont try to force it. Get the proper tool like an impact screwdriver or take the wheel to some mechanic who has one. Best of Luck.
